Go to YouTube and do a search for "RV hot water bypass valve"... Most campers are the same, or close enough that you can figure it out.

If you know where your water heater is found on the outside of the trailer-
then figure the valve(s) are typically found on the other end of that.
Go inside and look for a panel with screws that you would remove
to access the rear of the WH.
If your WH is located right next to the pass thru storage then look in
there for a panel.

Have you found the inside access point to your hot water heater? Usually there are arrows showing which way the valves should be facing for winterization. You want to make sure the valve allowing cold water ( should be a blue line ) into the water heater is turned to the opposite position from where you have been using it.

You will know when it is in the correct position when you open your hot water heater plug and water does not flow out at a high rate. Make sure you release the pressure relief valve first or you will be sprayed.

You are obviously lucky to be living in an area where you haven't had to winterize yet. It is 8* here in south Jersey this morning. UGH!

Good luck,

on my 05 Cardinal, it is to the left bottom of the water tank. It is slightly hidden by one of the water pipes. Hope this helps.
